The soap paste dispenser illustrated in the accompanying drawings has a body portion l which is provided in its upper part with an upwardly-opening socket 2 which is adapted to receive the neck 3 of a discardable soap paste container 4 made of moulded paper, pulp, metal, glas or other suitable material. The container 4 is supported in the inverted position when the body i is mounted ready for use, as shown in Figure 1. In the lower part of the body I a horizontally disposed cylinder 5 is provided which extends from the front rearwards, the front end of the cylinder 5 being closed-in permanently by an end plate 6. bore 1 of the cylinder the rear of the body I is made with a bore 8 which is aligned with the cylinder bore! and is closed by a flanged bush 9. The open rear end of the cylinder 5 communicates freely with the main chamber In which leadsdirectly-through a wide inlet opening ll to the interior of the socket 2 which is fashioned, as described later, to engage the neck 3 of the soap paste container 4.

" Behind the body chamber It and the socket 3 surmounting said chamber the body I is'formed with an integral-housing 12, open at the back and at the bottom. Transversely within the upper part of this housing I2 a pin I3 is supported horizontally in a pair of lugs Misee Figure 2) and upon the pin I3 is freely suspended, by its upper end, an operating lever l'5. The lower'part of the lever l5 extends through the open bottom of the housing l2 so as to project below the body I. Intermediately of its length the operatin lever I5 is provided with an aperture IB for-the passage therethrough of the rear end of a. piston rod H, to which'the lever i5 is pivotally connected by means of a cross pin l8 supported in a pair of bosses 19 on the lever I5. Part of the rear half of the rod i1 is slidably supported in the bore 20 of the flanged bush 9 and a coiled compression spring 2|, encirclingthe rod [1, is interposed between the flange of bush 9 and the inside face of the lever l5 so that the lever l5 is-norrnally forced to the limit of its stroke rearwards, as indicated in full lines in Figure 1. The extent of forward swing of the operating lever I5 is fixed, being determined by the maximum compression of the spring 2|. ward swing of the lever 15, however, is variable, being determined by the setting of an adjusting screw 22 mounted on a tongue 23 on the lever l5. The tongue 23 extends beyond the point of pivotal suspension of the lever 15, said adjusting screw 22 being adapted to contact with the interior surface of the housing l2 to arrest the swinging lever l5. Hence the length of stroke of the piston rod 11 may be varied, but any variation is made by regulating the position of rest of the lever (5, so that the operating lever lfi'always swings to a constant forward position, as indicated by chain-dotted lines in Figure l. On'the fronthalf of the piston rod 11 two elements of a piston assembly are secured, namely, a cut-off closure 24, preferably of a resilient nature, such as a disc of felt, leather or a suitable rubber, in which case the cut-off closure 24 is clamped between a pair of stiff washers 25 fixed along the front half of the piston rod- II,

To facilitate machining of the The extent of rear- 4 and a spider plate 26, or equivalent perforated element, secured on the forward extremity of the piston rod ll. The cut-01f closure 24 and the spider plate 26 are adapted to co-operate with the opposite ends of a thick ring 21 which is free to slide within the bore 1 of cylinder '5.

On the underside of the front end of the body I an internally screwed boss 28 is provided, from the top of which an outlet port 29 leads into the front end of the cylinder 5. Into the boss 28 is screweda nozzle 33 of metal or other suitable rigid material in which is nested a moulded rubber nipple 3 I. The nipple 3! has a flat-sided tip 32 (see Figure 9) pierced by a slit 33 which constitutes a discharge orifice and which because of the inherent elasticity of the rubber of which the nipple is made, is normally closed, that is, the discharge orifice is self-sealing. The tip 32 is received within the centrally disposed circular opening 34 of the hollow nose 35 of a nozzle 33 (see Figure 10), the circular shape of the opening 34 permitting the flat-sided, slit nipple tip 32 to stretch to a limited extent to allow discharge of the paste or liquid being dispensed. Openings 36 are provided in the wall of the nozzle noze 35 for the reception of a tool to facilitate assembly of the nozzle 33. The nipple 34 has a flange 31 which is clamped between the top face 38 of the nozzle 33 and the roof of the hollow boss 28.

The rim of the neck 3 of the inverted bottle 3 is clamped down on to a rubber gasket 39 which is backed by a metal or other substantially rigid washer 43. The washer 43 is seated at one point on the top of a. small boss 4!, surmounting a larger boss 42 having the bore 8 in which the flanged bush 3 is mounted. The washer 40 is also supported by a ledge 43 encircling the inlet ll to the body chamber Ill. The rubber gasket 39 and washer 46 are made to fit snugly within the socket 2, but they are not secured in position and thus can be readily removed for purposes of cleaning or replacement. The clamping action is effected by the engagemerit of a number of circumferentially-spaced inclined lugs 24 on the bottle neck 3 with a complementary set of lever lugs 45 within the socket 2. The circumferential spacing of socket lugs 45 is such as to admit freely of the passage therebetween of the bottle neck lugs 44, partial rotation of the body i relatively to the bqttle 4 causing the lugs 44, E5 to engage. The inclination of the lugs 44 causes the bottle neck 3 to be forced hard against and so compress the rubber gasket 39, thereby providing a liquid-tight seal between the bottle 5 andthe body I of the dispensing apparatus.

Because of the manufacturing tolerance which must be allowed for in the position of the bottle neck lugs 64 in relation to the rim of the bottle neck 3 it is important to be able to raise or lower the surface of the rubber gasket 3-9 with which the bottle necklrim contacts and the necessary adjustment can be readily effected by selecting gaskets 39 and/or washers 46 having suitable thicknesses, bearing in mind that the angle of inclination of the bottle neck lugs 44 largely determines the degree of compression required in the rubber gasket 33. In order to increase the range of adjustment the ledge 43 may be constituted by the outer end of one of a series of interchangeable ring-like liners. If desired, an interchangeable slip-in liner of this character may be securable within a plain cylindrical socket by fixing means which are inaccessible when the dispenser is mounted in a position of s'e th li erb ina rme i with s m a the socket lugs 45- and; with a ledge similar toledge 43; for supporting a rubber gasket 39" with or without a backing washer 40-,

For the purpose of" preventing unauthorised removal of; the bottle 4 from the body- I the 41 provided in an integral bottle locking block 4s -formediin the upper partof the housing; I2 in; such a; positionthat one end ofsaid bolt 46 project into the socket 2 of the bodyl' in line with the" bottle; ne k lugs 4 so that; when thus projecting-little or no reverse rotation of" the--bottle- 4 relativelyto the body I is-possible. The bolt 46'- is normally urged" by acompression spring 49 into the unlocked position excess outward movement of bolt 46 being prevented by thefixed cross pin- 50 which is adaptedto abut one end of= a recess formed in the bolt '46: The spring 4% is accommodated ina counter-bore inwhich is slidablethe head 52 of bo1t46.

"The bolt 46 is automatically moved; against the opposition ofspring 49, into the bottle locking position (see Figure 6) and retainedtin that position as the result of mounting the body.

inverted bottle 4, to thewall plate iceiiects locking of the bottle 4 to the body i-by means or" bolt 46 in the manner already described. The manner of locking the body I to the wall plate 54 by using a suitable key to operate the bolt 62 has also been described.

When the apparatus is to be operated to dispense a quantity of the substance stored in the bottle 4, for instance, soap paste, the operating lever is engaged by the hooked fingers of one hand and the lower end of the lever pulled forward. The piston rod l'i, acting against the resistance of its spring 2 1, moves forward the cutofi closure 24 and the spider plate 25 or the piston assembly, thereby causing the closure 24 to close the central aperture of the ring 2'1, which thus traps within and in front of the piston assembly a charge of soap paste. A piston assembly such as that illustrated will be found to operate efliciently even though the soap paste may have crystallized, as it may do at lowternperatures. Continued pulling of the operating lever l5 causes the closure 24 to urge forward the whole piston assembly including 'slidable ring 27, with the result that soap paste is pressed through outlet 29 into the interior of the nipple 3| held in the nozzle 34, thereby expanding the nipple 3i to open the slit-like discharge orifice 33 so thatthe soap paste can. now be expelled through said orifice 33, the soap paste being received,if desired, in the upturned palm of the same hand as that by means of which the operating lever I5 is being pulled. It will be appreciated that up to the limit of its stroke when the maximum amount of soap paste is dispensed, the extent to which the piston rod H is moved determines the amount of soap paste dispensed. The maximum amount of soap paste dispensable in a single full-stroke movement ofxthe piston is regulated in the embodiment described by adjusting the screw 2-2 on lever l5. Thequantity of soap paste dispensed could also be preadjusted by varying the tension of the piston spring, the maximum swing of the. operatinglever, the relative position of the piston, the thickness of the cut-oil closure or in any other suitable manner. In designing a dispenserof the construction'illustrated it isimportant to proportion the operating lever (5 so that the forward limit of stroke of the piston assembly is reached when the lower end of the operating lever is at a distance of about one and a half inches from the discharge orifice in order to ensure that thedispensed charge of soap paste is delivered on to the fingers or in the palm of the upturned hand bywhichthe lever i5 is being pulled.

Whenthe pull of the operating lever liis relieved the piston spring 2! operates to move rearwardly the operating lever 15, the pistonrod H with the cut-ofi closure and a spiderplate 26, which latter returns the ring 21 to its normal position. The return movement of the piston assembly relieves the pressure on the compressed mass of soappaste-thacylinder 5 is not com-V.

8 pletely emptied at each operation -and the rub-' oer nipple 3i self-sealsits discharge orifice 33. The nipple 3i and its nozzle 34 are made detachable and may he made interchangeable with other nipples having orifice-forming slits of various sizes. The inverted bottle 4 may be protected by placing over the bottle a suitable casing, which may have a depending tongue which is adapted to engage with and be locked to the wall plate. In this case the lugs M and 45 and the locking bolt 46'may be dispensed with. If such a bottleenclosing casing is used it may be made so as to terminate at a distance above the body of the apparatus so that the neck of the bottle is visible beneath the casing. If the bottle 4 is made of glass it can readily be judged when the bottle will be emptied and replacement necessary.
